tain new and useful Improvements in Lineand Space Indicating Mechanism for Typographical Machines, of which the following is a specification.

This invention relates to line and space indicating mechanism for typographical-machines, the object of the invention being to provide instrumentalities o fra simple and effective character by which the operator of such a machine can readily determine the state or condition of the line both with respect to the matrices, type or their equivalent and Spaces. The line indicating means and the spaceindicating means may, however, in

some instances beused separately, although I prefer to employ them together.

in the drawings accompanying and forming part of the present specification I have shown in detail one of the several convenient forms of embodiment of the invention which to enable those skilled in the art to practice the same, will be set forth fully in the following description. I do not limit'myself to this particular disclosure; 1 may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings:

In Letters Patent No. 1,118,298 granted tome November 24, 1914, for a line-indicating mechanism for typographical machines, is shown a line indicating element operative with the. assembler-slide of such a typographical machine. As will be inferred the present machine comprises a movable lineindicating element and while as will hereinafter appear, this line-indicating element is movable between the keyboard or between the space bar and the copy carrier or pan, this is not always necessary. As intimated there is a space-indicating element and while this space-indicating element may be located in any desirable place, I prefer that it be between the space-bar and the copycarrier, in that the field to be covered by the operator in setting matrices, type or their equivalents and spaces is of the smallest compass. The line-indicating element so far as its general character and mode of operation are concerned, ispractically the same as in the Letters Patent mentioned. The space indicator, however, is actuated with or by thespace bar Broadly, therefore, one of the features of the invention is a space indicating element operative in some suitable manner with its space bar. There are in fact many fundamental points of novelty, as will more particularly appear in my claims. In the construction shown and hereinafter described, the purpose of the spaceindicatin element is to show the expansive possibilities of a line. This space-indicating element is advanced each time the space-bar is operated, each step of the space-indicating element being equal to the maximum expansion of a space, by virtue of which the operator'can determine by glancing at the said space-indicating element, the expansive possibilities of a line.

With the foregoing general observation it is now proper to refer more in detail to the drawings. In Fig. 1'1 have shown parts of a typographical machine such as that employed for setting matrices. This machine comprises a keyboard as 2, a space bar or key as 3, a copy carrier, pan or tray as a and an assembler slide as 6.

As already observed the two indicating elements may be located in any convenient tion 16.

w i e place, but the best result as will be cred, are obtained by positioning them between the space bar 3 and the copy pan 4:. The indicating elements and certain cooperative devices are preferably mounted in a suitable casing as 7 which as shown is of practically "t -form in cross section and which may have fastened to it, brackets as S to be attached by screws or otherwise, to the frame of the machine, in the interval between the space-bar 3 and copy-pan i. The front of the casing 7 consists of plates 8. 9 and 10, the plates 8 and 9 being removably held in place by screws or otherwise and the plate or cover piece 10 having a lower stationary section also held in place by screws, and an upper swinging section, which upper section can be swung back to obtain access to the interior of the casing for a purpose that will hereinafter appear. In the cover-piece 8 is a longitudinal slot 11 through which the line-indicating element hereinafter more particularly described can be seen, said slot or sight opening 11 being intersected at one end thereof, by the slot or second sight opening 12 through which the space-indicating element can be read. The line-indicating element is denoted by 13 and the space indicating el ment by it, the line-indicating element being adapted to traverse in. a practically straight line the field or background or fixed indicating portion 15 while the space-indicating element traverses the field or fixed indicating por- To facilitate reading of the two indicating elements the fields may be white and the indicating elements black, although this is a detail. As will hereinafter appear the two indicating elements move step by step in opposite directions, the advancing movement of the indicating element 13 being toward the left in Figs. 2 and 5, while the advancing movement of the indicating element 1% is toward the right in said two views.

The line-indicating element 13 may be operated in any desirable manner, although the means shown for this purpose and now to be described are satisfactory. Said line indicator 13 as shown consists of an upward projection or pointer fastened suitably to the forward end of the rod 16 connected in some convci'iicnt manner to the forward end of the rack 17, the rod 16 inclosed by the casing T constituting practically a plain continuation of the rack which projects through an opening in one closed wall of said casing and is slidably mounted in the channeled guide member 18 rigid with said wall, said guide member having duplicate foiwardly extending lugs 19 perforated to receive the shaft 20 to which is pinneo or otherwise suitably fixed the pinion 21 in mesh with the 'gucncc hein oat when the shaft 20 is inc-indicating element 13 eeth of the racl; 17. the cone through the described parts will be operated.

shown, between the boss and the tube, the

shaft 20 being inclosed jointly by the tube and boss all illustrated best in Fig. G. Threaded into the upper end of the tube 23 is the depending boss 24- of the tubular guide member 25 cut away or slotted to receive the pinion 26 which meshes with the rack 27, the tubular guide member 25 being rigid with the bracket 28 fastened by screws or otherwise, to the framework of the ma chine. The pinion 28 is loose on the shaft 20, although normally it is rigidly connected therewith. so as to rotate with said shaft. The means shown for rigidly connecting the pinion with the shaft will be hereinafter described. with said shaft 20, it follows that on the turning of said pinion by the rack 27. the shaft 20 and consequently the pinion 21 will be also rotated to effect the motion of the lineindicating element 13 in the manner described. The rack 27 is connected at its forward or inner end with the bracket 29 which in turn is connected with the assembler-slide 6. Normally therefore, when the assembler-slide 6 moves the line-indicating element 13 acts in unison therewith through the intermediate mechanism forth. The advancing movement of the assembler-slide 6 in the construction shown is in the same direction as that of the line-indicating element 18. It will be assumed that both of them are in their primary positions. On the introduction of a matrix or type into the line, the assembler slide 6 is advanced one step, a corresponding movement naturally occurring" with respect to the line-indicating element 13, by reason of the connections therebetween. As will be understood the line-indicating element may be of a radically different character. it is not essential that mechanism such as that alluded to need be interposed between the two parts for efiecting the operation of the lineindicating element by or through the action of the assembler slide.

In typographical-machines involving an assembler-slide the length of line varies. and I provide means for adjusting the relation between the assembler-slide and the line-in- Xlicatin element 13. so that the two parts "When the pinion 26 is rigid J eml' independent relative adjustment of the assembler slide and line indicating element.

The shaft 20 has a stop or abutment thereon, the collar 30 answering satisfactorily in this respect, the thumb-nut 31 threaded onto said shaft presenting a convenient meens for normally pressing the pinion 26 against the collar, so that under open ting conditions the shaft 20 and pinion rotate as one, the pie ion as will he understood being disposed leetween the collar and not. The shaft 20 its upper encl is provided with the operating thumb-piece 82. llhen the length oi line has been determined, the not 81 will he bachecl away from the pinion 26 so that the shaft 26 can run th ee in the pinion. This permits the inclepentlelt movement or ecljustment of the line-indicating element 13 and assembler slide 6, the aclgustment of the line-indicating element 13 being accom- L iimgh the operating; member 82, "While the assen'ihler slide 6 can be directly adjusted. hen the necessary relative adjustments are ohtsincd the not 31 Will be manipulated to cl mp the pinion 26 against the collar 30.
